Hello,

There's currently a ticket that suggests that the requirement for external 
validation be removed.  Today, if example.com has an RUA that points at 
example.net, the latter must create a record as such:

example.com._report._dmarc.example.net TXT "v=DMARC1"

The original thought was that a bad actor could overwhelm a target with 
unrequested reports.  It seems in reality, most report generators only send 
once per day.  Additionally, there appear to be some generators who ignore the 
absence of these records.

https://tools.ietf.org/html/rfc7489#section-7.1

We'd like to have discussion wrapped up in about two weeks or so.  Again, thank 
you for your participation.
